DNSCrypt/dnscrypt-proxy

README

A flexible DNS proxy, with support for modern encrypted DNS protocols such as DNSCrypt v2 including Post-Quantum DNSCrypt (DNSCrypt 2026), DNS-over-HTTPS, Anonymized DNSCrypt and ODoH (Oblivious DoH).

Available as source code and pre-built binaries for most operating systems and architectures (see below).

DNS traffic encryption and authentication. Supports DNS-over-HTTPS (DoH) using TLS 1.3 and QUIC, PQDNSCrypt, DNSCrypt, Anonymized DNS and ODoH
Client IP addresses can be hidden using Tor, SOCKS proxies or Anonymized DNS relays
DNS query monitoring, with separate log files for regular and suspicious queries
Filtering: block ads, malware, and other unwanted content. Compatible with all DNS services
Time-based filtering, with a flexible weekly schedule
Transparent redirection of specific domains to specific resolvers
Optional hot-reloading of configuration files (disabled by default from v2.1.10)
DNS caching, to reduce latency and improve privacy
Local IPv6 blocking to reduce latency on IPv4-only networks
Load balancing: pick a set of resolvers, dnscrypt-proxy will automatically measure and keep track of their speed, and balance the traffic across the fastest available ones.
Cloaking: like a HOSTS file on steroids, that can return preconfigured addresses for specific names, or resolve and return the IP address of other names. This can be used for local development as well as to enforce safe search results on Google, Yahoo, DuckDuckGo and Bing
Automatic background updates of resolvers lists
Can force outgoing connections to use TCP
Compatible with DNSSEC
Includes a local DoH server in order to support ECH (ESNI)
